Application filed November 22, 1919, Serial No. 339,896. Renewed October12, 1922. Serial no. 594,202.

To r/l/ lf/lCm, it may concern:

Be it known that I, Enwann c. DnLsING,

is shown in the accompanying drawing wherein:

Figure 1 is a perspective view of the knife opened out; I

Fig. 2 is a similar view showing the knife closed up; i

Fig. 3 is a section taken transversely of Fig. 2;

Fig. 4c is a fragmentary detail showing the construction at the hingedend of the handle; and

Fig. 5 is a detail in perspective of the outer end of the blade carrier.

The present knife comprises three distinct parts-21 blade 6 securedwithin a carrier 7 which is pivoted to a handle 8. As shown, the blademay be of the usual kind that is used in a safety razor, but, ifpreferred, may be formed diflerently so long as will answer therequirements of this invention The handle, in the form shown, may bemade of sheet metal, which is bent in channel formation with its edges 9preferably bent upon itself (see Fig. 3), a clearance be ing providedbetween these edges for the reception of the blade 6. At one end thehandle terminates in an eye portion 10 having at one point a notch orindentation 11 formed adjacent its outer edge. Atthe other end of thehandle, best illustrated. in Fig. 4, the outer walls terminate short ofits bent over inner walls so as to provide shoulders 12, and the innerwalls which extend therebevond terminate in ears 18 having apertures t es as a 7 Te Pr v dea g eWe-Y within which the blade may be received. Asbest shown in Fig. 3, one edge of the blade is provided with areinforcing strip 18 adapted to lie within the channel of the carrierand to prevent withdrawal of the blade therefrom except by an endwisemovement. As a means of locking the blade within the carrier, 1 haveshown one of its sides 16 to be cut away as at 19 (see Fig. 5), itsother side along the inturned edge 17 being provided with 9, lug orprojection 20 adapted to spring to a position ahead of the blade whenthe latter is secured in place. In order to remove the blade from thecarrier, it is merely necessary that the projection 20 be sprung awayfrom an interfering position I ahead "or the blade.

The walls of the carrier at its opposite end are suitably formed toco-operate with the ears 13 to hingedly connect with the handle, ashoulder 21 being further provided to abut the shoulder 12 (see Fig. 1).In open position, as shown in this figure, the end of the carrierextends laterally of the handle to atford upper and lower abutmentsagainst which the fingers may rest to maintain the parts againstclosing, thus obviating the necessity of a spring for this purpose. henthe blade is closed within the handle, as indicated in Fig. 2, aprojection. 22 that extends from the carrier is adapted to seat withinthe notch 11 of the eye 10, and may be unseated only by slightly springthe eye, thereby tending to retain the blade within the handle when thedevice is folded up.

The construction of this knife is exceedingly simple, and inexpensive.It permits of ordinary razor blades to be used, and to be replacedreadily whenever desired. Such advantages, of course, are not attainablein the usual knife constructions. Accordingly I desire that theprinciples of this invention, as exemplified in the precedingdescription or as may be otherwise embodied, be included within thescope of this patent, particularly as defined by the claims following:

I claim:

1. A knife having, in combination, a handle formed of sheet metal thatis bent-t0 provide a channel with the edges thereof bent inwardly uponthemselves but spaced apart from each other an appreciable distance, acarrier also formed of sheet metal that is bent to provide a channelwith the edgesthereof bent towards each other but terminating apart fromeach other an appreciable distance, one of the sides of the carrieradjacent one end being cut away and the edge upon the other side of thecarrier being provided with an element projecting toward said cutawayportion, a

carrier adapted to provide a stop for the opposite end of the blade, thespace between the bent edges of the handle being adapted to receive theblade when the carrier is folded upon the handle, substantially asdescribed.

2. A knife having, in combination, a handle of channel formation, a car'ier hinged to the handle, and also of channel formation with its edgesbent toward each other, a portion of one carrier side adjacent one endbeing cut away, and an element being projected toward said cutawayportion from the edge upon the opposite side of the carrier, and a bladeprovided on its rear edge with an enlargement and adapted to slidinglylit within the carrier, the projecting element acting to spring ahead ofthe blade when the latter is in iinal position within the carrier so asto normaily prevent dislocation of the same, substantially described.
